Passive safety surveillance, case series, and observational studies reported the occurrence of thrombosis with thrombocytopenia syndrome (TTS), including thromboses that occurred at unusual sites (ie intracranial or cerebral, and intraabdominal thromboses), after receipt of adenoviral vector-based COVID- vaccines, noting that no such association with COVID- mRNA vaccines has been established.
